Abstract

This paper provides a contribution for NS-3 consisting of a new tool for generating Internet traffic. This tool is based on the Poisson Pareto Burst Process (PPBP), a Long-Range Dependent (LRD) model for network traffic. The PPBP model provides a simple and accurate network traffic generator that matches statistical properties of real-life IP networks. We have implemented this model in NS-3. We evaluate the computing performance of this PPBP implementation. Our results show a moderate overhead introduction in terms of memory needs and a roughly identical cost in CPU time as compared to a simple Poisson traffic generator.
